CONSTRUCTION OF CANAL-BOATS.

To all whom t may concern.'

Be it known that I, ANsoN JUDsoN, of the town of Unadilla and county of Otsego and State of New York, have invented a new and useful Improvement in the Construction of Canal-Boats to be Propelled by Steam o1' other Power; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to accompanying drawing and letters of reference marked thereon and making a part ofthis specication.

Figure lst is a cross section showing the plan of a boat constructed of wood or iron, or partly of wood and partly of iron straight on the bottom and of a size adapted to the canal and locks where used. A, is a square tube extending longitudinally from stem to stern and as large in diameter as one-fourth the width of the boat or thereabout. The bottom of the boat forms the lower section or partition of said tube, see end views Figs. 3 and 4L. y

Fig. lst is a straight continuation of said tube and forming a part of the outer and lower bottom oiI said boat from stem to stern and in connection with the sides of said tube ormsa funnel shaped aperture at either end for the ingress and egress of the water equal to the path of the boat in its passage through the water.

Fig. 2nd: F, is a cope formed by the eX- tension of the top of the tube as indicated by the dotted line, G, t-o aid in concentrating the water in its ingress and egress to and from said tube and to prevent the escape of the water from said tube by the action of the wheel.

Having thus fully described a boat to be propelled by steam or other power on canals I now set forth my claim.

I do not claim the tube 'or the ingress and egress of the water through said boat as a motive or propelling power or the use of the wheel as described to force the water through said tube. But

What I claim and desire to secure by Letters Patent is- The wide opening in the bow and stern of the boat extending to or near the full width of the boat and as low as the bottom substantially as and :tor the purposes described.
